Many thanks for your comments, Kenneth.

Yes, I lost nearly all of the code by the headcrash and this frustrated 
and paralyzed me for a longer while. I lost nearly all the code but not 
my memory about the creation of the scene. So after a while I restarted 
the project from scratch since I still took it for a fine idea.

And yes I used scattering media. I made some mistakes and we discussed 
them here in February 2019 in this thread. Thomas and Alain gave some 
very valueable hints for improvment. Many thanks to them again.

Best regards
Michael
